WASHIN G-MACHIN E T0 at! whom it may concern:

Be it known that I, CALVIN JACKSON, a citizen of the United States, and a resident of the city of Reading, in the county of Berks and State of Pennsylvania, have invented certain 11\V and IlSG lflll IIHPIOYQHHIIIS in \i ashing-l rlachines, of which the following is a specification.

My invention relates to washing machines having a rotary agitator, and my object is to provide a simple construction employing a onepiece rotary agitator-frame with curved-rod crank shaft having a. vertical shaft portion which is readily and satisfactorily mounted in the lid of the tub and a horizontal portion serving as a permanently secured crank handle for the agitator.

The invention is fully described in connection with the aeconi 'ianying drawing and is specifically pointed out in the claim.

Figure l is a sectional elevation of a washing machine embodying my improvements. .l ig. 2 is a plan View of the removable bearing collar showing the inclosed shaft in section on the line 2 2 of Fig. l.

The tub o and lid 5 are of ordinary construction. The latter is provided with an enlarged agitator-shaft aperture 0, and with upper and lower shaft-bearing rings (1 d secured thereto; said rings being also pro vided with enlarged shaft apertures c and with reversely arranged ball-race grooves The agitator frame has a crank-shaft 7L fixed thereto to form a one-piece device; said shaft consisting of a curved rod of round cross-section, having a straight vertical portion it extending upward from the ball-race hub g of the agitator frame through and above said bearing rings, and a horizontal handle portion h with curved connecting portion If. A handle is removably secured to the portion h In mounting the one-piece agitator frame Specification of Letters Patent.

and crank shaft, in the lid Z), the curved-rod shaft is readily passed through the enlarged apertures of the lid and bearing rings, so that the lid rests upon anti-friction balls re placed in the race-ways of the agitator hub g and lower ring d. To carry the agitator I employ a bearing-collar n having a race-way n and an aperture n the main portion of which is concentric with the raceway n but which is made oblong, in the direction of a set-scrcw opening a, so as to enabl the collar to be freely strung upon the shaft by passing it over the horizontal and curved portions if /L to the vertical port-ion 71., where it is adjustably fixed by means of the set screw, upon the interposed anti-friction balls on.

In my improved construction the one-piece frame and crank shaft prevents any possible loosening or disengagement such as ordinarily involves considerable trouble; and in connection with the attached agitator pegs p is readily stored in the tub a when disassembled by removing the bearing collar n and antifriction balls.

What I claim is:

In a washing machine the combination with a lid having upper and lower shaftb airing rings fixed thereto and enlarged shaft apertures therein, of a one-piece rotary agitator-fra me with curved-rod crankshaft, a. vertical portion of said shaft extending through and above said shaft-bearing rings; and a. bearing collar with oblong opening therein strung upon said curved-rod crank-shaft and cent ally secured thereto above the upper slnift-bearing ring, substantially as set forth.

In testimony whereof I allix my signature, in the presence of two witnesses.

CALVIN JACKSON.
